We have nothing to do with life in the aggregate--that
great bulk of duties, responsibilities, struggles, and
trials which belong to a course of years. We really have nothing
to do even with the nearest of the days before us--tomorrow. Our
sole business is with the one little day which is now
passing. Its burdens will not crush us--we can easily carry them
until the sun goes down. We can always get along for one short
day--it is the projection of life into the long future, which
dismays and appalls us.

Each day is, in a certain sense, a complete life by
itself. It has
its own duties,
its own trials,
its own burdens,
and its own needs.
The very best we can do for the perfecting of our life as a
whole, is to live the one day well.

We should put all our thought and energy and skill into the duty
of each day, wasting no strength, either in grieving over yesterday's
failures--or in anxiety about tomorrow's responsibilities.

This lesson makes life easy and simple!

"Therefore do not worry about tomorrow, for tomorrow will worry
about itself. Each day has enough trouble of its own." Matthew
6:34
